- Polar Coordinates as a Definitive Technique for Evaluating Limits
A lot of questions say "use polar coordinates" to calculate limits when they approach 0 0 But is using polar coordinates the best way to evaluate limits, moreover, prove that they exist? Do they account for every single possible direction to approach a limit, for example, along a parabola Specifically, if I were to show that
- Easy way to compute logarithms without a calculator?
I would need to be able to compute logarithms without using a calculator, just on paper The result should be a fraction so it is the most accurate For example I have seen this in math class calc
- Evaluating $ \\lim\\limits_{n\\to\\infty} \\sum_{k=1}^{n^2} \\frac{n}{n . . .
How would you evaluate the following series? $$\\lim_{n\\to\\infty} \\sum_{k=1}^{n^2} \\frac{n}{n^2+k^2} $$ Thanks

- Is there a way to get trig functions without a calculator?
In school, we just started learning about trigonometry, and I was wondering: is there a way to find the sine, cosine, tangent, cosecant, secant, and cotangent of a single angle without using a calc
- limits - Evaluating $\lim_ {x\to 0}\frac {e^x+e^ {-x}-2} {1-\cos x . . .
Compute without using L'Hospital's Rule $$\\lim_{x\\to 0}\\dfrac{e^x+e^{-x}-2}{1-\\cos x} $$ I thought of simplifying the limit as shown below \\begin{align} \\lim
